Navistar agreed to pay a civil penalty of $52 million and to prevent at least 10,000 tons of oxides of nitrogen (NOx) emissions to resolve its violations of the Clean Air Act (CAA).

In July 2015, the United States government through the Department of Justice (DOJ) filed a lawsuit against Navistar. The federal government alleged that the company illegally introduced approximately  7,749 heavy-duty diesel engines (HDDEs) that were not covered by the certificate of conformity issued by the Environmental Protection Agency (EPA) and did not meet emission standards.

Additionally, the U.S. government also alleged that Navistar marketed and sold those HDDEs installed in its branded International trucks as EPA-certified model year 2009. In fact, Navistar completed manufacturing and assembling those HDDEs in 2010.

Those HDDEs were actually model year 2010 and must have an EPA-issued certificate of conformity showing compliance with the 2010 emissions standards. Navistar violated the CAA for selling those engines that did not meet 2010 emissions standards, according to the Justice Department.
